Question

Identify the graph, vertex, and azis of symmetry of the function
f(x)=4x^2-4x-2

Answer 1

the vertex's x coordinate of a polynomial in the form ax^2+bx+c is at -b/(2a), so that tells you the axis of symmetry (x=?)
the vertex is when you plug in that x value that you just found from -b/(2a) into the equation
